KLEINFELDER <br /> On November 26, 2003, the water level in monitoring well LMW-6 was measured and the <br /> ' field technician noted heavy machinery operating in the area. The monitoring well was <br /> reported as "Gone" on December 16, 2003. The installation of LMW-6 was constrained <br /> by the boundaries formed by the current farming operations (ie. near the southwest <br /> corner of the row crop field and east of the orchard). Plate 3 shows the location of LMW- <br /> ' 6 and the alignment of Golden Valley Parkway and the Ag Field 52a depicted over an <br /> aerial photograph taken in June 2001. Plate 4 further depicts the location of LMW-6 in <br /> relation to the site construction and road alignments in June 2004. Presently (August, <br /> ' 2005), the estimated former LMW-6 site is located beneath a home pad on the west side <br /> of Golden Valley Parkway. The remaining monitoring well PVC casing, if any, is believed <br /> to be buried beneath graded fill. Plate 1 also shows the location of LMW-3 in relation to <br /> ' the current site configuration. <br /> Piezometer P-3 was last monitored on November 11, 2004. During May 2005, <br /> ' subsequent site visits revealed that P-3 had been demolished due to grading and <br /> construction activities. Presently (August, 2005), the estimated former P-3 site is located <br /> beneath residential home pads or paved streets west of Golden Valley Parkway. The <br /> ' location of P-2 is depicted on Plate 1 in relation to the current site configuration and on <br /> Plate 4 (aerial photograph, June 2004). The remaining piezometer PVC casing, if any, is <br /> believed to be buried beneath graded fill or a paved road. <br /> Piezometers P-7 and P-8 were last monitored in April 2004. In May 2004, both <br /> piezometers were found to have been ripped from the ground. It appeared that the <br /> piezometers were demolished due to farming activities as they were located within a <br /> ' orchard at the time. Only the monument of one piezometer and a portion of 1-inch PVC <br /> casing were found on the ground surface. Presently (August, 2005), the estimated <br /> former piezometer sites are both located due south of Golden Valley Parkway. Plate 1 <br /> ' depicts the locations of P-7 and P-8 relative to the current site configuration. The <br /> remaining piezometer PVC casing, if any, is believed to be buried beneath graded fill. <br /> ' CONCLUSIONS <br /> Based on Kleinfelder's reconnaissance efforts and aerial photograph evaluation, it <br /> appears that all the former wells are located in developed areas outside the boundaries <br /> of the constructed recycled water land application areas. It appears that all wells have <br /> been destroyed during grading operations performed either during farming or during <br /> construction efforts related to residential or commercial development. Because the <br /> ' former wells are located outside land application areas and because the former wells <br /> are now located underneath roads or graded fill, there does not appear to be significant <br /> potential for the former wells to serve as conduits for recycled water to reach deeper <br /> groundwater. <br /> I <br /> C20-4099-04.E02/ST05R1057/JDZ:Iv Page 4 of 5 <br /> ©2005 Kleinfelder, Inc.
